INHAL|NG DEVICE.

SPECIFICATION forming part of Letters Patent No. 353,220, dated November23, 1886.

Application filed March 10, 1886. Serial No. 194,711.

To all whom it may concern:

Be it known that I, MAR-MADUKE WELnon HOBBS, of Richmond, in the countyof Wayne and State of Indiana, have invented certain Improvements inInhalers, of which the fol- (which has been allowed) for an inhaler anddescribed and claimed.

In the accompanying drawings, Figure 1 is a central vertical section ofmy improved instrument. Fig. 2 is a central longitudinalsection of theair-induction tube. Fig. 3 is a horizontal section of the instrument online 2 z, Fig. 1. Fig. 4 is a central longitudinal section .of theair-eduction tube and the valve attachment.

The can A is designed to contain warm or hot water, which may beintroduced and discharged through an opening closed by a removablescrew-cap, N. Within this can A is arranged the receptacle B, for theether or other substance to be inhaled. It is attached to and pendentfrom the top of the can, and of such dimensions that a narrow spaceexists between the sides and bottoms of the two receptacles A B, so thatthe inner one, B, is mainly surrounded by the heating agent when theinstrument is in use. There is an opening in both the top and bottom ofcan A. Avertical tube, 0, is attached to the bottom around the openingtherein, and projects up through the bottom of the inner receptacle, B.Near the top of said tube a wire-gauze diaphragm, L, is arranged, and anarrow transverse bar, J, is fixed in the bottom. The stem or rod 1? ofthe valve E passes through these parts LJ, and is screw-threaded whereit works through bar J, to adapt it to be adjusted up or down to shiftthe position of the valve E, as required, to regulate the admission ofair through the tube D. A milled disk, 0, is attached to used.

the lower end of the valve-rod for use in r0- tating it. The tube D ispendent from the top of the can A, and has a screw-flange around theopening in said top. The valve E isa fiat imperforate plate or disk,having a vertical flange, a, around its edge, the function of which willbe presently explained.

Around the inner side of receptacle B are arranged several narrowshelves or annular trays, F, having their inner edges turned up- I wardto adapt them to hold the liquid to be inhaled.

The manner of using the instrument is as follows: The can A is firstfilled with water'of the temper required to produce rapid evaporation ofthe inhalent. The latter is introduced through tube D; or, by invertingthe instrument, it may be poured in through the lower tube, 0. Thislatter method is preferable, since the liquid is thus collected aroundthe base of tube D, and when the instrument is reversed to its normalposition the liquid fills the trays F. To insure this result, they aremade of gradually-increased width from the top downward, as shown. Thevalve E being now adjusted so as to leave the inner ends of both tubes 0D open, it is obvious that air drawn through the instrument will becomecharged with the inhalent. By adjusting the valve up or down the volumeof air thus passed through in a given time may be regulated at will, forsuch adjustment will cause the valve to approach more or less closely tothe adja cent end'of one of the tubes, 0 and D. When the inhalation hasbeen completed, the water is discharged, and a cork stopper may beinserted in the mouth of the tube D, and the valve E adjusted downwardto close the inner end of tube 0. Thus the volatile inhalent will beconfined, so that no loss will occur from evaporation while theinstrument remains unant after each use of the instrument, it is onlynecessary to screw out the tube D.

In my former invention, before referred to, I have provided a fixedplate in place of the present adjustable valve or disk E, and such platehas a pendent flange to prevent any of the liquid poured in through tubeD from passing out through the lower tube, (3. In this case the flangearound valve E will not only prevent such result, but also prevent theIf it is preferred to remove the inhalliquid passing into tube D whenpoured in through the lower tube, 0.

What I claim is- 1. In an inhaling-instrument, the combination, with thereceptacle B and an air-tube projecting into it, of a valve or diskwhich is 3. In an inhaling-instrument, the combination, with theair-induction tube and air-eduction tube-and receptacle B, of the diskE, ar-

ranged between the inner ends of these tubes and having a peripheralflange which projects in each direction or toward each tube, as shownand described, to operate as specified.
